Plutchik proposed a classification approach for emotional responses. He considered there to be eight primary emotions— anger, fear, sadness, disgust, surprise, anticipation, trust, and joy. Plutchik argues for the primacy of these emotions by showing each to be the trigger of behavior with high survival value, such as the way fear inspires the fight-or-flight response. He suggested 4 relationships that pair these emotions together: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation. Additionally, his model directly connects the idea of a circle of emotions to the color wheel. Like colors, primary emotions can be expressed at different intensities and can mix to form a variety of emotions. The theory was extended to provide the basis for an explanation for psychological defense mechanisms; Plutchik proposed that eight defense mechanisms were manifestations of the eight core emotions.

We researched and verified how each emotion moves the human body.
